Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external contact sensors are used to monitor enclosure status, then real-time status monitoring is achieved, but additional electrical power and batteries are required increasing maintenance
Solution Approach 1:
The strike plate uses passive magnetic contactors that detect enclosure status without requiring external power sources. The magnetic field interaction between the contactor in the strike plate and the magnet in the leaf provides automatic status detection, eliminating the need for batteries or external power supply while maintaining continuous monitoring capability.
Solution Approach 2:
The patent replaces active electronic sensors requiring power with passive magnetic sensing mechanisms. The magnetic contactor system detects the presence or absence of the leaf magnet to determine enclosure status, substituting mechanical/magnetic fields for electrical power-based sensing.
2Reliability
If external accelerometers are installed on the surface to sense break-in attempts, then tamper detection capability is provided, but the sensors become visible and susceptible to tampering or deactivation
Solution Approach 1:
The accelerometer is integrated inside the strike plate housing, merging the security sensing function with the existing mechanical strike plate structure. This consolidation hides the accelerometer from external view while maintaining its tamper detection capability, as the strike plate itself serves as the protective enclosure for the sensor.
Solution Approach 2:
The accelerometer is nested within the strike plate body, placing the sensitive component inside the existing structural housing. This nesting approach protects the accelerometer from external tampering while utilizing the strike plate's inherent structural integrity for security.
3Reliability
If integrated sensing technology is incorporated into the strike plate, then real-time monitoring and security alerts are enabled, but the device complexity increases
Solution Approach 1:
The strike plate is designed as a multi-functional device that simultaneously provides mechanical striking function, magnetic status sensing, accelerometer-based tamper detection, and wireless communication capabilities. By consolidating these diverse functions into a single integrated unit, the patent reduces the overall system complexity compared to using separate components.
Solution Approach 2:
The patent introduces a microcontroller unit as an intermediary that coordinates all sensing and communication functions. This central controller simplifies the system architecture by managing magnetic contactor readings, accelerometer data, and wireless transmissions from a single point, reducing the complexity of coordinating multiple independent systems.
4Adaptability or versatility
If conventional strike plate dimensions and anchoring are maintained, then installation compatibility is preserved, but space for integrated electronics is limited
Solution Approach 1:
The strike plate internal structure is optimized with localized cavities and compartments specifically designed to house electronic components. The back portion of the strike plate contains recessed areas that provide adequate space for the microcontroller, accelerometer, magnetic contactor, and battery while maintaining the external dimensions and mounting hole patterns of conventional strike plates.

AI summary
The present invention relates to a smart electronic strike plate for windows and doors, which can sense and communicate in real time the status of the enclosure. The strike plate comprises a body (10) adapted to be installed in the door or window frame, two contactors (1, 2) that sense the position of the leaf bolts, and a communication module (3) configured to send this information to a cloud platform. In addition, the communication module integrates an accelerometer, which senses break-in attempts or impacts, generating security alerts. The system is powered by a battery compartment (4), which houses two AAA batteries, providing a battery life of more than two years. Due to its design, the strike plate is installed without modifications on the enclosure and allows remote monitoring via a mobile application, improving the security and control of windows and doors.
